shadow copy - only 1 copy appearing

[Guest Sleb]

Hi,

 

I have seen this problem a couple of times on windows 2003 servers even

though this is not a common issue (different clients). When I look at shadow

copies of a drive, I see only 1 copy. It looks like everytime it does a copy,

it deletes the old ones. I've checked the schedule, the quota,

deactivate/reactivate with default options, all the options, everything is

fine and even redoing the shadow copy configuration did nothing. If I do a

shadow copy manually, I now see 2 shadow copies. The one made by the schedule

and mine (I've done a couple manually and can see all of them). But at the

next schedule, I will see only 1 copy which is the last one made

automatically. The other automatic copy and the manual ones dissapearing.

 

I've also checked with the command vssadmin that everything is fine and no

errors in event viewer. On the server I am having the issue ritght now, I see

multiple copies for the C: drive but only one for the D: drive (so basically

don't have the problem for the C: drive). I have configured and used Shadow

copy a lot over the years and always use default values which is fine with me.

 

Any ideas?

 

Thanks

AFAIK, the number of copies retained, depend on the available disk

space....are you running low?

Yes, well that is: not only

 

It relies on (if set in registry)

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Settings\MaxShadowC

opies

 

as well as the maxsize which you can specify like this:

 

vssadmin resize shadowstorage /for=<vol_letter:>: /on=<vol_letter:>

/maxsize=XXGB
